PC4711-W-TY
Single-Phase WiFi Smart Energy Meter
UniClip Lite entry model: Tuya single-phase clamp meter with two 300 A CTs, 90-277 V input, bidirectional usage and solar metering every 15 seconds.
Overview
PC4711-W-TY (UniClip Lite) is the entry point of the single-phase range: one circuit, two CT clamps, data on a phone. Clip the open-type CTs around the existing cables, pair over BLE, and the Tuya App shows consumption, solar export and history by day, week, month and year. Nothing is rewired and no circuit is interrupted.
It covers a single-phase service at 230 V AC nominal with a 90-277 V input range and up to two CTs from 80 A to 300 A, and leaves out the two options the other models add: the Ethernet port and the relay output.
PC4711-W-TY Platform and Integration Notes
Offline storage, so a dropout is not a gap in the record. Readings are held locally and re-reported automatically once the network returns.
Export and history are the change from the previous generation. The free Tuya app on earlier models kept 7 days of history and could not export hourly data; this meter exports, with history by day, week, month and year.
Accuracy with its bands stated. Voltage ±1%; current ±1% at rated current and ±2% at low current, banded per CT rating rather than quoted as a single figure.
Tuya App, and Home Assistant. Readings and history are read in the Tuya App, and the same meter integrates with Home Assistant — the pairing the official UniClip model comparison gives this platform.
Bidirectional by default. Grid import and solar export are measured by the same device, so a PV installation needs no second meter.
PC4711-W-TY Limits and What to Specify Instead
- Three-phase, split-phase or 3P3W supplies — this is a single-phase meter. Three-phase services need the PC4713 range, and a 3P3W or delta supply specifically needs the PC4713-W-E-TY/3W.
- A third metering channel — this model takes up to two CTs. Three single-phase circuits on one device is the PC4711-W-TY/3CT.
- Ethernet — not fitted. The PC4711-W-E-TY adds a 10/100 Mbps port.
- Relay output — not fitted. The PC4711-W-TY/R and PC4711-W-E-TY/R carry the dry-contact relay.
- Your own server as the destination — the Tuya range reports to the Tuya Cloud. PC4711-W (Wi-Fi) and PC4711-W-485 (Wi-Fi plus RS485) are the Open API models.

Key Benefits
Two Open-Type CTs, No Rewiring
Up to two split-core CTs from 80 A to 300 A clip around the existing cable, with nothing cut and no supply interruption.
Data Export With Day-to-Year History
Export from the App with history by day, week, month and year, with offline storage that re-reports automatically after a dropout.
Wi-Fi + BLE Pairing, Tuya App
Wi-Fi 2.4 GHz with BLE-assisted pairing, then live readings and remote management in the App.
Erase Data and Re-Range CTs From the App
Data erase, remote reboot and CT setting from the App — no site visit for a configuration change.
Ideal For
Common deployment scenarios where Single-Phase WiFi Smart Energy Meter delivers the most value.
Single-Phase Home with Solar
Grid import and solar export measured in one device, with history by day, week, month and year in the App.
One Circuit or Load
Two open-type CTs clip on without rewiring, so a single load can be metered without touching the supply.
Apartment Submetering
Readings are taken from a phone, with export when a landlord or tenant needs a record.
Retrofit Metering
No circuit is cut and no supply is interrupted, which suits occupied buildings.
Owner-Managed Monitoring
Tuya App and Home Assistant integration without a platform project.
Distributor and OEM Programmes
Neutral standard units, with branding and packaging available.
